MECHANICAL MOTOR.

Specification of Letters Patent.

Patented Aa-'.5,'1921.

Application filed October 13, 1919. Serial No. 330,330.

T 0 all whom it may concern:

Be it known that 1, DAVID ZAIDEN, a citizen of the Russian Government,and residin at New York, New York county, New Y ork State, have inventedcertain new and useful Improvements in Mechanical Motors, of which thefollowing is a specification.

This invention relates to mechanical motors and its object isto utilizespring power and secure a greater number of revolutions for a drivenwheel and cause the wheel to run a longer time than if it was driven bythe ordinary train of wheels, and a further object of the invention isto eliminate a number of the gear wheels generally used. These and otherobjects and details of the invention are more fully described in thefollowing specification, set forth in the appended claims andillustrated in the accompanying drawings, wherein:

Figure 1 is a side elevation of the motor,

Fig. 2 is an end view of the same.

For convenience of illustration, the motor is shown mounted on a base 5,and adapted.

to impart motion by means of a pulley 6, on the shaft 7 of the fly wheel8, but it is evident that if applied to some toy car or applied to theoperationof some light machinery, other frame work and driving means maybe utilized.

The frame 9, which is mounted on the legs 10, and has the tie bars 11,and shafts 12, 13, 14 and 7 to unite the two sides of the frame, thelatter carrying the pulley and fly-wheel as above stated.

The shaft 12, carries the spring 15, the only gear wheel 16, and theusual ratchet and pawl which are not seen on account of the spring. Thegear wheel 16, meshes with the pinion 17, on shaft 18, and which alsocarries the escapement wheel 18, while shaft 1 1, carries the escapement19, whose dogs alter nately engage the teeth of the wheel 18 and therebylimit the release of the spring 15.

Arms 20, are carried by the escapement and support a cross piece 21,with a lug 22, to which is loosely attachedthe pitman 23, and whoseupper end is penetrated by a pin or stud 24, extending from the hub 25,of the fly wheel 8.

lVhen the fly wheel isvgiven a start, it releases one of the dogs of theescapement and the tooth at the other dog, acting on its roundedsurface, pushes down the other dog. The impetus of the wheel causes acontinuous movement and the force of the spring on the escapement wheelcauses the dogs to rise carries the mechanism and fall and the pitman 23to propel the fly wheel. With the release of each tooth, the wheel 8revolves once and as the spring 15 may be of such length and strength asto rock the escapement, it follows that there will be 'many revolutionsof the said wheel and its petus increases its speed until it rotatesvery fast. I

Adjacent. the shaft 7 is a brake consisting of a stiff coil spring 26 atthe upper end of a lever 27 that is pivoted to the upper end of frame 9on the stud 29 provided with a tension spring 28 to retain the lever inany desired position after it has been set by the handle 30. While theshaft 7 is rotatingthe pressure of the spring head 26 thereon withsufiicient force Wlll finally completely check the movement of the wheeland shaft, and stop the motor. 7

To start the motor after the spring has been wound, the lever 27 may beoscillated I and the friction of the head 26 on the shaft 7 will besuflicient to start the device in the desired direction. I 1

It is obvious that other arrangements or modifications may be resortedto without de-.

parting from the essential features above described'or from the scope ofthe appended claims. i

What I claim is: Y

1. In a mechanical motor, the combination of power means, a gear wheeldriven by the latter, a shaft with a pinion to mesh with the gear wheel,an escapement wheel on the shaft, an escapement dog, an arm projectingfrom the upper side of the dog, a fly wheel, a pitman connecting the armand the fly wheel, and a flexible brake adapted'to operate on the shaftof the fly wheel.

2. In a mechanical motor, the combination of a power spring, a gearwheel driven by the same, a shaft with a pinion that meshes with thegear wheel, an escapement wheel on the shaft, dogs pivoted above theescapement wheel, an arm projecting from the dogs and pivot, a flywheel, a pittangential to their.

man connecting the arm and the fly wheel, 7

and a brake lever with a flexible head to im inge the shaft of the flywheel.

n testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses, this 27th day of September, 1919.

Witnesses: DAVID SNYDER, J AMES F. DUHAMEL; 1

DAVID ZAIDEN.
